The Spinfusor MK-X is an explosive weapon used by the Juggernaut class in Tribes: Ascend. It can be unlocked for 160 Gold or 18000 XP.
"Many tribal warriors disdain the modified spinfusors issued them, and in protest have modified the Spinfusor MKDs to have performance similar to a standard spinfusor." In-Game Description
Operation
The Juggernaut's Spinfusor modification is nearly the same as the classic 'medium' Spinfusor used by the Soldier class. The MK-X trades the higher blast radius and lower damage of the Spinfusor MKD for performance almost identical to that of the Soldier's Spinfusor. Unlike the MKD, a direct hit from the MK-X will kill a full-health Pathfinder or Sentinel.
